FLUE-STOPPER.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed May 13, 1904. Serial No. 207,766.

To all LUhOTI'b it may concern: 1

Be it known that I, CARL A. RosELAND, a citizen of the United States, residing at Rock- 1 ford, in the county of Winnebago and State 1 of Illinois, have invented certain new and useful Improvements in Flue-Stoppers, of which the following is a specification.

The object of this invention is to construct l a flue-stopper in which the bails have a foldl ing connection with the plate and which have a partial free swinging movement. The remainder of their movement is against the 1 spring force of the bails, being sufficient to 1 hold the stopper in the flue.

In the accompanying drawings, Figure 1 is an isometrical representation of a flue-stopper containing my improvements in which the holding devices are folded. Fig. 2 is a similar representation in which the holding devices are opened.

The plate 1 is of the usual construction. The center portion of the plate has four ears, 2, 3, 4, and 5, formed of the material comprising the plate; but it is evident that the ears may be formed in any suitable manner.

The holding devices comprise two bails 6 and 7. The bail 6 is provided with the substantially right-angle bends 8, forming shouldered stops, sections 9 pointing toward one another having their free ends 10 turned at right angles to the sections 9 and parallel with the shoulder-stops 8. The ends 10 form end stops. The bail 7 has like shouldered stops 11, sections 12, and end stops 13.

The sections 9 of the bail 6 are located in the ears 2 and 3, and the sections 12 of the bail 7 are located in the ears 4 and 5, thereby -forming a pivotal connection between the bails and plate 1.

At Fig. 1 the bails are shown in their folded position and at Fig. 2 in their partial extended or open position.

The bails are moved into the position shown at Fig. 2 before force is applied to them. Either set of stops will serve to arrest the further free opening movement of the bails. The arms forming the bails proper will yield sufficiently to permit them to be inserted in the flue and when liberated their spring action will hold the plate over the flue-opening.

By permitting the bails to have a partial free movement but slight spring tension is necessary to hold the plate in proper position, which will present the plate in its normal condition over the flue-opening, whereas if excessive spring tension be imparted to the bails the plate will buckle and not properly cover the flueopening.

When the bails are folded, the stopper will occupy little space and can be closely packed for shipment.

I claim as my invention- 1. A flue-stopper comprising a plate, and two independent bails independently pivoted to the plate, each bail having a-partial free opening movement, and each provided with stops serving to limit suchfree opening movement.

2. A flue-stopper comprising a plate,.and two independent bails independently pivoted to the plate, each bail having a partial free 0 ening movement, and each provided with s ouldered stops serving to limit such free opening movement.

CARL A. ROSELAND.
